Overview

CVE-2025-2874 affects the User Submitted Posts WordPress plugin (versions up to and including 20240319) and involves a Stored Cross-Site Scripting vulnerability via admin settings. The vulnerability was discovered and disclosed on April 3, 2025, and affects multi-site installations and installations where unfiltered_html has been disabled (NVD CVE).

Technical details

The vulnerability stems from insufficient input sanitization and output escaping in the plugin's admin settings.

Impact

When exploited, this vulnerability allows authenticated attackers with administrator-level permissions to inject malicious web scripts that execute in users' browsers when they visit affected pages. This could potentially lead to session hijacking, credential theft, or other client-side attacks (NVD CVE).

Mitigation and workarounds
